Beschreibung
Zusammenfassung:	In a furnace installation for producing silicon carbide in an intermittent operation, carbon electrodes arranged in the bottom of the furnace. A horizontally arranged resistance core is electrically connected to the carbon electrodes by vertically extending elements of an electrically conductive material having a higher specific conductivity than the core material. The resistivity of the connection between the electrodes and the core and the current passing through the connection produces a temperature lower than that necessary to form silicon carbide, and thereby prevents the destruction of the connections and electrodes normally caused by the downward movement of the silicon carbide roller.
